Abstract
An adjustable, articulable platform (10), changeable to and from a "U" shape to an "H" shape, is attachable to the distal end (17) of an articulable support arm (12) of a transport vehicle. The platform (10) is arranged to adjustably surround an elevated chimney (90) on at least three sides thereof. The platform (10) comprises: a lower anchor plate (20) centrally disposed within an elongated lower support frame; a rear anchor plate (26) connected perpendicularly to the lower anchor plate (20), the rear anchor plate (26) centrally and connectively disposed within an elongated rear wall frame (38), comprising bridging portions of the platform. A right sidewall frame (30) and a left sidewall frame (32) is connected to respective end portions of the elongated rear wall frame. A right slidable sidewall (44) is slidably disposed within the right sidewall frame (30), and a left slidable sidewall (46) is slidably disposed within the left sidewall frame (32), to permit forward and rearward adjustability to side rail and floor portions thereof around an elevated structure for supporting personnel and equipment therefor. Those side rail and floor panel portions are also adjustable transversely to squeeze closed together or slightly further apart according to the width of any chimney or the like. Such sideways adjustment is accomplished by supportive engagement of the mid portion of the rear wall frame (38) and floor panel of its adjacent wall and floor panels.
